Abstract
Gummed labels having outlines corresponding to top and bottom views of integrated circuit packages include numbered lead locations as seen from both the top and bottom of a particular integrated circuit package. A simplified schematic diagram located on the portion of a label corresponding to the integrated circuit package body indicates connection of an integrated circuit to the respective leads. Part numbers and brief descriptions and commercial integrated circuits are printed on the labels. A plurality of unused labels are removably attached to a backing sheet, and are peeled off and placed on a working sheet to enable an engineer or technician to easily make diagrams or printed circuit board layouts without having to refer to a manufacturer's catalog.
Claims4
A method of making a schematic block diagram of an electronic system including a plurality of integrated circuits, said method comprising the steps of:
- a. removing a plurality of gummed labels from a backing sheet, said gummed labels each having an upper surface, said upper surface having a plurality of numbered lead tab areas thereof, said lead tab areas being numbered in respective sequences in accordance with the sequences of leads as viewed from the bottom sides of each of a plurality of respective integrated circuit packages;
- b. attaching said gummed labels to a sheet on which the schematic block diagram is to be made;
- and
- c. drawing a plurality of lines connecting predetermined ones of said lead tab areas on said sheet, said lines representing electrical conductors of the electronic system.
